Mainly because I trust short term trends over long term projections.
For example if I can flip a stock at every two-four weeks at 10-20% I can make more money then waiting til May on a project return.
Lets say XSPA goes up and down three times during that may time frame. If I sale at projected small values I can get a compound interest effect on my money instead of waiting for a big score.
And yes that is a Pit Bull Pulling my sleigh... after all I am A Ill Reindeer.
